Vinegaroon eating a superworm

Today I fed my vinegaroon (uropygid) a larva of the darkling beetle (Zophobas morio).
I had fed it a larvae earlier on, but this time I managed to see the animal capture and eat it.
On the earlier occasion, the vinegaroon noticed the vibrations the dropping of the
superworm caused, and started to feel around with its first pair of legs, which are
highly specialized sensory organs. Or like Esme said: like a blind man using his stick.

But the superworm managed to hide from view, which wasn't a problem for the vinegaroon,
which was able to find it very fast, but the catching and eating was hidden from view
as well.

But this time I dropped the larva close to the vinegaroon, which just grabbed it, and
started to eat the "worm". What amazed me was that the larva didn't move like crazy like when
it had been captured by a tarantula spider for example. Maybe the vinegaroon just had a firmer
grip.

In the above picture you can see a small part of the bottle cap that I use to provide
the vinegaroon with a water source. It had turned it upside down earlier that day. Also
visible in the picture is a scorpion that is housed in the terrarium to the left of the
one housing the vinegaroon.

I decided to carefully remove the bottle cap before taking more pictures. In the above
picture you can clearly see the two specialized legs. They are longer and thinner then
the other 3 pair. Both pictures were taken with the lowest flash setting of the
Sony Cyber-Shot DSC-S600.

The above picture was made with flash off and ISO was set to a value of 100. A small
flashlight was used to provide some lighting.
